DOOR OPENER Specification of Letters Patent.

AND CHECK.

Patented Nov. 14, 1916.

Application filed. Apri1.7, 1916. Seria1No. 89 ,716.

To all whom it may concern:

Be 'itknown that I, GEORGE B. CLAY, a citizen of the United States,residing at Jenkintown, county of Montgomery, and State of Pennsylvania,have invented a certain new and useful Improved Door Opener and Check,of which the following is a specification.

This invention relates to a combined dooropener and check and has moreparticular relation to an improvement upon the device for which LettersPatent were granted to me under date of July 18, 1911, the same beingnumbered 998,324.

The principal object of the present invention may be said to reside inthe providing of a device of the character stated in which is combinedefliciency, cheapness of manu facture and maintenance, simplicity of andaccessibility to working parts, lightness of structure consistent withmaximum strength and the provision for adjustability of parts.

Other and further objects of the present invention reside in theproviding of general details of construction and in the arrangement andcombination of parts as will hereinafter more fully appear.

With these and other objects in view the invention consists of theimprovements hereinafter described 'andfinally claimed.

The nature, characteristic features and scope of the invention will bemore fully understood from the following description taken in connectionwith the accompanying drawings forming part hereof and in which:

Figure 1 is a sectional plan view illustrating the application of thedevice of the invention between a door and a doo-r-jamb. Fig. 2 is aview in elevation of Fig. 1. Fig. 3 is a sectional plan viewillustrating the locked position of th device when a door hasbeenopened. Fig. 4 is a face view of the adjustable stop shown in theforegoing figures. Fig. 5 is a plan view thereof. Fig. 6 is a View insection taken upon the line 6-'-6 of Fig.1 4, but drawn to an enlargedscale, and Figs. 7 and 8 are views of modified details-hereinafterreferred to.

For the purpose of illustrating my invention, I have shown in theaccompanying drawings one form thereof which .is at present preferred byme, since the same has been found in practice to give satisfactory andre liable results, although it is to be understood that the variousinstrumentalities of which my invention consists can be variously hingedas at-11 to a door-jamb- 12 and in practice adapted to be maintained inclosed position by a suitable door-bolt 13 usually releasabl by anoverhead cord and hand pull arrangement as is well understood in theart. Fixed to the inner face of the door 10 is an elongated horizontallydisposed metallic guide-way or track 14 preferably made up of a seriesof sections 14 secured to place by screws 15. Such sections 14 areflanged top and bottom as at 16 see Fig. 6 so that when a section isproperly positioned upon a door, grooves or channels 17 are presentbetween the innerface of the door and the inner faces of the flanges 16,the purpose of which will presently appear. The object of making theguide-way 14 in sections is so that adjustments to accommodate varioussizes of hinges maybe readily had from a standard type of guide-way. Ihave in mind the making of the trackway 14 in a single section as shownin Fig. 7 and alsohave in mind making thetrack-way 14 in twosuperimposed strips 14 considered in cross-sectlon as shown in Fig. 8instead of an integral flanged piece, Fitted to the guidewayv or track14 was to be adjustable there along is a stop 18 preferably embracing atwo-part wedge-shaped member made up of integral angular secti0ns'19and20 of which each section 19 is horizontally disposed and terminatesin a flange 21, said flanges being adapted to track within the aforesaidgrooves or channels 17 and of which each secti0n20 is verticallydisposed and the two substantiall ylabut centrally of the stop.

The two parts of the stop are clamped together upon the guide-way ortrack 14 1 when adjusted to proper position, by means of a bolt 22, soas'to normally maintain a, fixed position as will be readily apparent byan inspection of Fig. 6, the guide-way 14 clamping the flanges 21 to thedoor 10 and the bolt 22 clamping the angular section to the guide-way.Fixed to the door-j'amb 12, as by brackets 23,is a pivot 24 mounted uponwhich so. as to be operated for partial swinging therearound isone'section of a horizontally disposed jointed arm 25 the other section ofwhich yieldingly mounted upon the-door, at least one of said sectionsbeing provided with means operative for engaging the aforesaid stop 18upon opening of the door 10 to arrest return movement thereof. Inpractice, the section 26 of arm 25 which moves around the fixed pivot 24is formed of a tubular socket 27 supported by a bracket 28 upon saidpivot and extended. from which is a straight portion terminating in agenerally curved portion to provide a substantially sickle-likeconfiguration, see Figs. 1 and 3. This is so that as the door is openedthe edge 29 thereof will not engage the swinging section 26. Operativelyconnected between the swinging section 26 and the pivot 24 are coiledsprings 30 normally under tension for causing said section to swing inan arc of a circle upon release of the door. The free end of saidsection 26 is provided with a roller 31 for tracking upon the guide-way14 including the stop 18. Adjacent the free end of said section thereisalso located a lug 32 connecting with which is the section 33 ofjointed arm 25. This section embraces an elongated bar of circularcross-section fitted into and bolted to a socket 34 which socket'isforked and has pivotal relation as at 35 with said lug 32.

The free end of the bar is screw-threaded to,

receivea nut 36 and a spring 37 is positione d on said bar immediatelyadjacent to said nut to form a cushion between a slotted guide piece 38fixed to the door 10 and said nut when the doorreaches its predeterminedextent of outward movement. Obviously by adjusting the nut 36, thismovement may be lengthened or shortened as desired. 7 It is to be notedat this point that as the roller upon the free end of the section 26 ofarm 25 always tracks upon its guide-way l4 and is thus supported and asthe section 33 has pivotal relation with the lug 32 upon said section,the former sectlon may always maintain a position substantially inparallelism with the door 10 considered in plan without dangerof saidbar becoming bent or distorted. Obviously the nut 36 and stop 18 i areadjusted so as to obtain a predetermined cooperation of parts.

Assuming the door 10 to be-closed as shown in Figs. 1 and 2, the jointedarm 25 is substantially in parallelism with said door considered in planwith the roller 31.. resting uponthe outer end of the guide-way 14,spring 37 free from compression and springs 30 under tension. With therelease of bolt 13, the door swings upon its hinges thus breaking thearm 25 at its joint and causes roller 31 to track upon its guide-way,ride over stop 18 and'again drop to the guideway in the rear of saidstop. The section 33 of arm '25 has meanwhile been drawn backward, thuscausing compression of spring 37 against guide-piece 38 to'limit theforward swing ofthe door. The roller 31v isnow in abuttingposition withthe rear of stop 18 and it is to be noted in this respect'that' the rearof the stop is curved as at 39 so that said roller may be readilyaccommodated and the section 26 positively locked. In this position, thedoor 10 is arrested against return movement. This position is clearlyillustrated in Fig. 3, in which position it will be observed that thegenerally curved section of arm 25 is free of the door edge 29 as beforedescribed. The curved portion also forms a convenient medium for closingthe door 10 as the same forms a grip to readily accommodate the hands ofthe operator. To close the door, the operator grasps the curved portionof said section and by pulling the same toward him, frees the roller 31from the rear of said stop 18 whereupon the roller once more tracks uponthe guide-way 141 and the door 10 may be readily closed.

It will now be apparent that I have devised a novel and usefulconstruction which embodies the features of advantage enumerated asdesirable in the statement of the invention and the above descriptionand while I have in the present instance shown and described thepreferred embodiment thereof which has been found in practice to givesatisfactory and reliable results, it is to be understood that the sameis susceptible of modification in various particulars without departingfrom the spirit .or scope of the invention'or sacrificing any of itsadvantages. 7
